EXTENSION FURNITURE FOR PRINTERS. a 4

Application filed April 7, 1921.

To all '20 item it m (1.12 concern:

Be it known that I, HARRY H. HANCOCK, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Extension Furniture for Printers, of which the following is a specification.

This invention relates to extension or adjustable furniture for the use of printers in looking up type within the chase; and one of the objects of the invention is to provide such furniture with two counterpart members, which are connected together to form a unitary article of manufacture, so that they may be longitudinally extended for substantially the entire length of the furniture, but without danger of separating the members, and so that there can be no relative transverse movement of the members. Another object of the invention is to provide simple, durable, efiicient and prac-' tical extension or adjustable furniture for printers.

Prior Patent, #1,126,910, dated February 2, 1915, and granted to Henry E. Streebig for self-adjustable marginal furniture for printers, is a type of printers furniture over which the present invention embodies certain improvements. In the said patented device, the two members of the furniture may not only be moved transversely of each other, but they can be separated longitudinally. In other words, the said device cornprises two members which can be separated entirely from each other, no matter what the adjusted length of the furniture may be, that is, whether the furniture'is entirely collapsed, or is extended. One of the objects of the invention, therefore, is to pre sent advantages which the said patented device does not.

The specified objects of the invention being some of those in view, the invention consists of certain features of construction and combinations of parts, to be hereinafter described, and then claimed, with referenceto the accompanying drawings showing one embodiment of the invention, in which Figure l is a perspective view of the improved printers furniture, showing the members thereof Collapsed or distended?

Serial No. 459,344;

of printers furniture. which may be employed under the present invention for locking up type, etc, in a printers chase in place of the hundreds of sizes of ordinary furniture now in'use. Of course, the number in a set of my improved furniture may be varied. The different sizes of furniture, under the present invention, have specific dimensions, except that the longitudinal dimension need not be specific. The vertical distance between the parallel upper and lower surfaces of the furniture shown in Fig. 1, in the extreme. is less than typehigh, as otherwise various objections would be encountered in printing. The transverse dimension between the parallel, opposite, vertical side walls ofthe furniture is in any of the units oftype measurement employed by printers. The unit may be of a pica measurementor nonpareil, or the measurement may be in fractions of an inch, so that the widths of the different sizes of furniture may be expressed as so many picas or fractions thereof. depending upon the size of the furniture. The furniture shown in Fig. 1 may be assumed to have a width of ten pica s, a length of fifty-eight picas when entirely collapsed, and a lengthof eighty-six pic as when fully extended, as thesedimensions would be proper for one size.

Referring to the drawings, except Fig. 3, there are two members 10 and 11, and the construction and shape of these members is such that they are counterparts of each other, so that it is only necessary to duplicate one of the members in order to have two members for. the complete article of furniture. These members are preferably composed of metal, such as an l oy mainly ttaining 1 body of each aluminum, as for instance, an alloy ofalu-V minum and copper, or the alloy may beef zinc and copper, and in fact, any suitable metal or alloy, or even suitable wood, etc.

The member 10 comprises in the a larger body portion provided with longitudinal tongue 12, which is shown as of the same length as the body portion of said member. The member 11 also comprises a larger body portion provided with a tongue 3 similar to the tongue 12. The larger -ember has opposite upper and lower walls 1%, 15, extending in parallel planes, and the said walls rereive between them, within a deep longitudinal recess 16, thecorresponding tongue 12 or 13, as the case may be.

In practice, each member, such as shown in Fig. 3, is preferably composed of one piece of metal so that an integral half of thefurniture is provided; or, if desired, the

tongue of the member be formed as an 1 extension of a strip which is placed between t'woopposite side pieces of metal, the three partsbelng spot-welded, and the form being substantially as shown in Fig. 3. Of course,

the said members may be otherwise con structed. It is preferred to make each of the members, such as shown in Flg. 8, by the diecasting process, I If two members, such as shown 1n 151g. 3, are placed together to produce an article of furniture as shown in F 1,.the proportions and arrangement of the parts and.

surfaces thereof will be asfollows: There will be a plane of'separation between tl e members 10, 11, at 17, which plane of separation extends longitudinally of the furniture and is formed by the vertical wall of the recess 16 of each member, the vertical inner wall of the tongue, extended in alinement from each member, and between the contactingsurfaces of said walls with the adjacent walls of the other member. Preferably, the height of these wallsis approximately half of the height of the furniture, and as the recess 16 in each member is rectangular, the tongue which fits therein is also made rectangular, transversely. furniture is rectangu ar in cross section, and the plane of se aeration 1'? is preferably mi; way between the opposite vertical or outer walls of the completed. articleof furniture and is parallel therewith. me ng the tongue of each member rec a size corresponding to the preferred dimensions of the rectangular recess to receive straight condition. 1

separation of the two members of the, furniture, and for preventing the relative trans verse movement of said members, are pro-l located at opposite sides of The entire article of and of ture might be subjected and to maintain its;

vided. These means preferably comprise a shallow groove 18 extending longitudinally of the lower surface of tongue 12 and a simllar longitudinal groove 18 on the under surface of the other tongue 13, These grooves extend parallel with the plane of separation 17 between the members of the furniture, and each groove is a little shorter than the length r the tongue, 12 or 13, in which it is formed. When each member is formed wlth a groove identically located, if the two members were tongue 12 thereof, with small pin, ud oi tongue 19, which is received inthe groove 18 of the ton ue 13. A corresoondingl lo to 1 1 L we) cated om 2011s )rovioeu on the bod )OltlOIl of the member 11, enter the groove 18 11 4 e n 1 1 T 1n the tongue 12 or the memoer in, in t e preferred construction, these pins will be the plane of separation 17. In any extended position of the members of the furnituraeach ofthese tongue-andgroove connections, '18, .19, and 18, 2%), supplement theaceuon of the other of them, in precluding lateral transverse separation of the two members away from the vertical plane of separation of the memhere at 17. Fusthermore, theouter end 21 of each groove 18 forms a stop or abutment for the pin or tongue that is received in the corresponding groove, so that the two members may not be entirely separated longitudinally, although they can be extended for nearly the full lengthof the two members.

Each of the pins or studs 19, 20, is prefer ably in the form of a rivet, which is driven in place after the two members are assembled, and the head of each rivet is finished s0 niture-when the two members are assembled; 7

push them together in longitudinal aline' ment. It is not necessary to use friction menace for binding the parts of the furniture together, as they are always held together by suitable mechanical means so that they can be handled as a unit.

It is preferred to provide the upper and lower surfaces of the furniture, that is, each member 10, 11, with transverse ribs-22 spaced at suitable intervals apart, and with longitudinal edge ribs 23 connecting the transverse ribs. The flat upper and lower surfaces of the ribs lie in parallel planes and define the height of the furniture so that the same shall be less than type-high.

It is obvious that the invention is susceptible to more or less modification without departing from the scope and spirit of the invention as defined in the claims.

What I claim as new is:
